Clone Windows hard drive with AOMEI Backupper Standard

To clone hard drive easily in Windows, it is suggested to use AOMEI Backupper Standard. Simple steps and intuitive interface make your hard drive clone effortless. But most of all, it’s free! This utility supports Windows 10/8.1/8/7/Vista/XP currently.

This freeware will clone only used part of the old drive by default. Therefore, it enables you to clone larger drive to smaller drive as long as the smaller drive can hold all data on the larger drive. In addition, it is capable to improve the performance of your SSD. Let’s see how it works!

Step 1. Select Clone from the left side. Then click Disk Clone. (To copy only OS to new drive, please use System Clone in AOMEI Backupper Professional.)

Cloning Your Data to a New Hard Drive in macOS
Our primary recommendation for transferring files from an old Mac OS X or macOS drive is performing a clean install of OS X (10.11.6 and under) or macOS (10.12.0 and higher) and migrate your data using Migration Assistant. For instructions please click here. Cloning is a viable option if installing a fresh copy of the OS and migrating your data is not an option.
Cloning is a destructive process that will erase the recipient drive, leaving the source drive intact.
The instructions below are for cloning from the original drive externally to a new drive inside a computer. In certain circumstances connecting the original drive externally is not an option. In those cases using an external hard drive as an intermediate is recommended. This process would consist of cloning the original drive while still inside the computer to a separate external hard drive, then installing the new drive and cloning the external hard drive to that new drive.
Booting into the recovery partition or OS install media
After you install the new hard drive, you will need to boot to the recovery partition on the original drive if OS 10.7 or later is installed. If OS 10.6.8 or earlier is installed, you can use the original OS install discs that came with the computer.
Power on the Mac while holding down the 'Option' key. This will display a boot menu that looks like the picture below. Click the drive icon that says 'Recovery' (OS 10.7 and later) or 'Mac OS X install' (OS 10.6.8 and earlier).
The number of drives listed will depend on the number of
bootable drives in your system.
Format your new drive
Once booted into the Recovery partition or installer disc, select your desired language. Next, open Disk Utility by navigating to the Utilities menu in the upper-left corner of the screen, then select Disk Utility from the drop down menu. Once in Disk Utility our detailed instructions for the formatting process can be followed:
Apple's Disk Utility (10.3.x to 10.12)

  2. Drag the old volume to the Source field.
